Answer:
D) Square root of 48
Step-by-step explanation:
We have to split the triangle in half and then multiply that by two for the answer. Then we use a²+b²=c² because the two triangles are right triangles, and we know b=4 and c=8, so a²+(4²)=8², or a²+16=64
a² would have to equal 48. a=√48.
X - 0.38x = 868......x is the same as 1x
1x - 0.38x = 868
0.62x = 868...now divide both sides by 0.62
x = 868 / 0.62
x = 1400 <==
